液(ye)(ye)體吸(xi)收(shou)(shou)(shou)法是利(li)用液(ye)(ye)態(tai)吸(xi)收(shou)(shou)(shou)劑對廢(fei)氣(qi)(qi)(qi)(qi)進(jin)行(xing)中(zhong)(zhong)和吸(xi)收(shou)(shou)(shou)，液(ye)(ye)體吸(xi)收(shou)(shou)(shou)法的(de)(de)特點是既能(neng)吸(xi)收(shou)(shou)(shou)有害氣(qi)(qi)(qi)(qi)體，又能(neng)除掉排(pai)氣(qi)(qi)(qi)(qi)中(zhong)(zhong)的(de)(de)粉塵。廢(fei)氣(qi)(qi)(qi)(qi)在(zai)(zai)與(yu)噴(pen)淋(lin)水(shui)觸(chu)碰(peng)的(de)(de)過(guo)程中(zhong)(zhong)，廢(fei)氣(qi)(qi)(qi)(qi)中(zhong)(zhong)的(de)(de)空(kong)(kong)氣(qi)(qi)(qi)(qi)污染物被水(shui)充足吸(xi)收(shou)(shou)(shou)，HCl等(deng)污染物可(ke)以通(tong)過(guo)在(zai)(zai)噴(pen)淋(lin)水(shui)中(zhong)(zhong)加入一定比例的(de)(de)NaOH使(shi)噴(pen)淋(lin)水(shui)呈堿性。在(zai)(zai)噴(pen)淋(lin)過(guo)程中(zhong)(zhong)，當(dang)水(shui)與(yu)尾氣(qi)(qi)(qi)(qi)觸(chu)碰(peng)時，會發生(sheng)(sheng)生(sheng)(sheng)化(hua)(hua)反(fan)應，中(zhong)(zhong)和HCl等(deng)氣(qi)(qi)(qi)(qi)態(tai)空(kong)(kong)氣(qi)(qi)(qi)(qi)污染物，循(xun)環(huan)水(shui)泵將循(xun)環(huan)往(wang)復水(shui)箱中(zhong)(zhong)的(de)(de)藥液(ye)(ye)泵送至是我凈(jing)(jing)化(hua)(hua)塔上部進(jin)行(xing)噴(pen)淋(lin)，從(cong)噴(pen)嘴出(chu)來(lai)的(de)(de)藥液(ye)(ye)產生(sheng)(sheng)細水(shui)霧，并與(yu)上游氣(qi)(qi)(qi)(qi)體產生(sheng)(sheng)觸(chu)碰(peng)，吸(xi)收(shou)(shou)(shou)氣(qi)(qi)(qi)(qi)體中(zhong)(zhong)的(de)(de)HCl，實(shi)現凈(jing)(jing)化(hua)(hua)處(chu)理的(de)(de)目的(de)(de)，凈(jing)(jing)化(hua)(hua)處(chu)理后的(de)(de)氣(qi)(qi)(qi)(qi)體直接(jie)從(cong)噴(pen)淋(lin)塔頂(ding)端(duan)的(de)(de)排(pai)氣(qi)(qi)(qi)(qi)管(guan)排(pai)出(chu)來(lai)，洗滌液(ye)(ye)在(zai)(zai)沉(chen)淀池中(zhong)(zhong)沉(chen)淀后進(jin)入循(xun)環(huan)往(wang)復水(shui)箱，再經酸霧凈(jing)(jing)化(hua)(hua)塔頂(ding)端(duan)的(de)(de)排(pai)氣(qi)(qi)(qi)(qi)管(guan)排(pai)出(chu)來(lai)噴(pen)淋(lin)水(shui)由循(xun)環(huan)泵提高循(xun)環(huan)往(wang)復應用。

1、在酸霧(wu)凈化塔運行前藥(yao)箱加滿水后，再(zai)(zai)加入(ru)15kg氫(qing)氧(yang)化鈉，將(jiang)其(qi)攪拌溶(rong)解。在加藥(yao)桶(tong)加滿水后，再(zai)(zai)加入(ru)20kg氫(qing)氧(yang)化鈉，將(jiang)其(qi)攪拌溶(rong)解。對風(feng)(feng)機、噴(pen)淋(lin)泵等(deng)設備進行檢查后，再(zai)(zai)啟(qi)動電源開關(guan)按鈕。當風(feng)(feng)機正常(chang)(chang)工作后可啟(qi)動噴(pen)淋(lin)泵，從觀察(cha)窗查看(kan)(kan)噴(pen)淋(lin)系統是否(fou)正常(chang)(chang)，查看(kan)(kan)設備是否(fou)正常(chang)(chang)工作。

2、在酸(suan)霧(wu)凈(jing)(jing)化塔運轉(zhuan)正常后噴(pen)(pen)淋(lin)藥(yao)箱一個月進行換水(shui)(shui)一次(ci)，防污(wu)(wu)網(wang)可(ke)拆下清洗干(gan)凈(jing)(jing)后再還原。加(jia)藥(yao)桶需要每天檢查(cha)一次(ci)是(shi)否(fou)需要增(zeng)加(jia)氫氧化鈉(na)（噴(pen)(pen)淋(lin)藥(yao)箱中的(de)(de)堿(jian)液PH值控制在8~10）。在觀察窗可(ke)觀察除(chu)霧(wu)膠花是(shi)否(fou)沉(chen)淀(dian)(dian)物過(guo)多（阻(zu)礙了酸(suan)霧(wu)氣體(ti)的(de)(de)上升(sheng)、噴(pen)(pen)淋(lin)堿(jian)液的(de)(de)下降），沉(chen)淀(dian)(dian)物過(guo)多可(ke)停機后排(pai)放干(gan)凈(jing)(jing)吸收(shou)塔內的(de)(de)污(wu)(wu)水(shui)(shui)至車間(jian)酸(suan)堿(jian)廢(fei)水(shui)(shui)收(shou)集管網(wang)，再加(jia)進清水(shui)(shui)用(yong)噴(pen)(pen)淋(lin)泵清洗干(gan)凈(jing)(jing)即可(ke)。保持吸收(shou)塔水(shui)(shui)位可(ke)供噴(pen)(pen)淋(lin)泵使用(yong)，不讓(rang)其空轉(zhuan)。
